COMBINED FLOUR BIN AND SIFTER.

SPECIFICATION forming part of Letters Patent No. 425,334, dated April 8,1890. Application filed January 31, 1890. Serial No. 338,797. (Nomodel.)

To a whom it may concern/.-

Be it known that I, GEORGE A. MARKHAM, of Goldwater, in the county ofBranch and State of Michigan, have invented certain new and usefulImprovements in Combined Flour Bins and Sifters; and I do hereby declarethe following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itpertains to make and use it, reference being had to the accompanyingdrawing, which forms part of this specification.

My invention relates to an improvement in combined flour and meal binsand sifters, and it consists in the combination and arrangement ofparts, which will be more fully de scribed hereinafter, and particularlypointed out in the claims.

The object of my invention is to produce a combined flour bin and sifterin which the operating parts are all supported in or upon a metallicframe of the construction hereinafter described, which is secured in thelower part of the bin.

The accompanying drawing represents a vertical section of an implementwhich embodies my invention complete.

A represents the bin, which may be of any desired shape, size, orconstruction that may be preferred, and which is provided with a loop,hook, or other device 13 upon one .side, so as to suspend it upon thewall or any other suitable support. The lower end of this bin iscontracted in size, as shown, and the sifting mechanism is located inthis lower end. Rigidly secured inside of the lower end of the bin A isa metallic casting or frame O,

which extends entirely across the bin and is provided with thedownwardly-extended portions D, which are provided with horizontalbearings, and the tubular bearing G, which extends vertically, as shown.The portions D are secured by rivets or otherwise to the bin A.Extending horizontally through these bearings is the cranked shaft 0,which has the beveled wheel I-I secured to it, and which wheel mesheswith the beveled wheel I, which is secured to the lower end of thevertical shaft J, which projects any suitable distance up into the bin,and to the upper end of which the stirrer L, of any suitableconstruction, is fastened. 'lvhen the shaft 0 is revolved by its handleor crank, the shaft J is also caused to revolve and the stirrer Lprevents the flour from clogging in the bin. This shaft J projectsthrough the bearing G, and has the brush P rigidly secured thereto, sothat the brush is caused to revolve over the top of the screen Q, whichis placed loosely in the lower portion of the bin and above the top ofthe casting G. The shaft J is held in an upright position by means ofthe tubular bearing G, so that it can have none other than a rotarymovement. The rotary movement imparted to the brush causes it to forcethe flour through the screen Q, and it then falls through the lower endof the bin A into the receptacle prepared to receive it.

All of the parts of this bin are made removable, with the exception ofthe casting O, and this can be made removable if so desired. i

\Vhen the bin is not in use, its lower end will be covered by means of acap, so as to keep dust and insects from getting into the flour or meal.

Having thus described my invention, I claim- 1. In a combined flour binand sifter, the combination, with the bin, of the casting C, which isplaced in its lower end and provided with the two horizontal bearings atits ends, and the tubular bearing G at its center, the horizontaloperating shaft, the vertical stirrer-shaft, and intermeshing gearssecured to each, the casting being made to form a support for theoperating parts of the sifter, substantially as shown.

2. In a combined flour bin and sifter, the combination of the bin, thecasting 0, provided with the bearings at its ends, and the tubularhearing or journal G at its center, the horizontal shaft 0, thegear-wheels II I, the vertical shaft J, the stirrer L, secured to theupper end'of the shaft, the brush secured to the shaft J, and the screenQ, substantially as shown and described.

In testimony whereof I affix my s gnature in presence of two witnesses.

GEORGE A. MARK HAM.
